IMPROVEMENT IN APPARATUS FOR MOLDING CLAY TOBACCO-PIPES.

Specification forming part of Letters Patent No. 182,951, dated October3, 1876; application filed March '29, 1876.

To all whom it may concern:

Be it known that I, JOSEPH G. OLIVER, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulApparatus for Molding Clay Tobacco- Pipes; and I do hereby declare thefollowing to be a clear and exact description of the nature thereof,sufficient to enable others skilled in the art to which my inventionappertains to fully understand, make, and use the same, reference beinghad to the accompanying drawings, making part of this specification, inwhich- Figure l is a top or plan view of the apparatus embodying myinvention. Fig. 2 is a transverse section in line w m, Fig. 1. Figs. 3and 4 are views of opposite ends thereof. Fig. 5 is a view of a detachedportion in the section y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention has for its object the molding of clay tobacco or smokingpipes; and it consists of a plunger, which is mounted on an axial frame,so that it may be set at various angles relatively to the set or angleof the pipe-bowl to be molded.

It also consists of a borer having rotary and sliding motions forpiercing the stem of the pipe, so as to form the bore thereof, the borerbeing mounted on an axial frame, so that it may be set at various anglesrelatively to the set or angle of the pipe-stem to be molded.

It also consists of the combination of an adjustable bowl-plunger and anadjustable stemborer, whereby the two parts may be adjusted relativelyto each other, so as to form both a bowl and its stem of any desired setor angle.

Referring to the drawings, A represents a frame or support, on which ismounted the main shaft B, to which power will be communicated in anywell-known manner. On the shaft B there is secured a cam, O, which isadapted to come in contact with a sliding portion or section a of themold D, which section, with the fixed section b, is supported on theframe A, the said sliding section receiving closing motion from the camO, and opening motion by means of springs or weights suitably applied,although the cam may be so constructed and connected to the said sectionas to impart motions thereto in both directions. On each inner face ofthe sections of the mold there will be impressed the shape of half ofthe bowl and stem of a pipe of the order known as smoking or tobacco. Drepresents a plunger, whose head is of the contour of the inner face oropening of the bowl of the pipe to be molded. Motions will be impartedto the plunger in the present case by means of an arm or rod, 0,connected to a yoke which encircles an eccentric, d, mounted on a shaft,0, which receives rotary motion from the main shaft or otherwise bysuitable intermediate gearing. To the frameA, at the end at which theplunger is located, there is pivoted a frame, E, which extends at aright angle to the longitudinal direction of the frame A, and on saidframe E there is mounted a borer or wire, F, which extends transverselyand toward the mold D. A portion of the borer passes through a sleeve,g, which is mounted 011 the frame, and carries a screw, feather, or key,h, which projects into a longitudinally-extending groove, k, in theborer, as more clearly shown in Fig. 2. The borer also passes looselythrough a bevel-gear wheel, m, which gears with a similar wheel, n,whose shaft 19 is mounted on the outer end of the arm E, and receivesmotion from an eccentric on the shaft 0 by means of a belt, band, orotherwise. To the borer there is secured a collar, 8, to which isconnected an arm, G, which receives reciprocating motions from aneccentric mounted on the shaft 6. By these means rotary andreciprocating sliding motions will be imparted to the borer.

As has been stated, the frame E is pivoted or has an axis at one end,whereby the frame may be raised and lowered, so as to impart difierentangles to the borer F.

In order to hold the frame in its adjusted position it has secured to ita segmental arm, H, formed with a series of openings, in which is fitteda screw, t, passing into the adjacent portion of the frame A. Thestandard or upright J has a pivotal connection to the frame A, so thatit may be moved laterally, and thus set the plunger at various angles. Aseries of openings, 0, will be formed in the standard, so that by a pinor screw, w, passed through one of the same into an adjacent plate theplunger will be held in its adjusted position.

In order that the gearing for the borer and plunger operate the same,regardless of the various adjustments thereof, the frame E and standardJ will be mounted at a common axis or point to the frame A, which axisor point in the present case is the shaft 0.

The operation is as follows: The mold will be opened and the clay fedthereto in any proper manner, care being taken to oil the clay or moldin order to prevent subsequent sticking of the clay to the mold. Powerbeing applied to the main shaft, the sliding section of the mold isclosed against the fixed section, thus molding the outside shape of thepipe. Then the plunger descends, thus forming the cavity of the howl,and the borer enters the stem of the pipe, so as to pierce the boretherein.

It will be seen that the borer has rotary and sliding motions, so as toproperly bore into or penetrate the stem of the pipe, and produce aperfect bore. The mold now opens, the plunger ascends from the bowl, andthe borer withdraws from the stem. The molded pipe may then bewithdrawn. A fresh supply of clay will be passed to the mold, the latterthen closes, the plunger descends, and the borer advances, theoperations being the same as has been stated.

When the set of the bowl is to be at an acute or obtuse angle to thestem, the standard of the plunger will be adjusted, so that when theplunger descends it will form the cavity of the bowl relatively to theangle at which the bowl is set. The stem may also be made at variousangles to the bowl. For this purpose the frame E will be adjusted sothat the borer F will advance or bore into the stem relatively to theangular direction of the latter.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a tobacco-pipe molding apparatus, the plunger, mounted on an axialframe, so as to be adjustable to the angle of the bowl to be molded,substantially as and for the purpose set forth.

2. The borer F, having rotary and sliding motions, and mounted on theaxial frame E, substantially as and for the purpose set forth.

3. In a tobacco-pipe molding apparatus, an adjustable bowl-plnnger-andadjustable stem borer or wire, combined and operating substantially asand for the purpose set forth.
